Solution

1. Preparation

Gather all necessary tools and parts.
Elevate the vehicle securely on jack stands and remove the wheels if needed.
Tools required: Jack, jack stands, socket set, torque wrench, pry bar, and possibly a suspension spring compressor.

2. Inspect and Replace Worn Components

Control Arms/Bushings:
1. Remove the control arm bolts using a socket set.
2. Inspect bushings for cracks or excessive wear.
3. If worn, replace bushings or the entire control arm as necessary.
4. Reinstall the control arm and torque bolts to manufacturer specifications (typically around 50-70 ft-lbs).
Struts/Shocks:
1. Remove the strut assembly by detaching it from the top mounts and lower control arm.
2. Inspect the strut for leaks or physical damage.
3. If damaged, replace the strut with a new unit.
4. Reassemble the strut, ensuring to torque the top mount bolts to the specified value (usually 15-25 ft-lbs).
Sway Bar Links/Bushings:
1. Remove the sway bar link bolts using a socket set.
2. Inspect the sway bar links and bushings for wear.
3. Replace any worn components and reinstall, torquing to manufacturer specifications.

3. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle off the jack stands.
Tighten all wheel lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
